Available on iOS and Android, the app is relatively easy to use. Once you've entered your destination you then have the option to invite your friends or family members to virtually accompany you home.

Conveniently, they don't need to have the app.

'Companion' keeps a close eye on you by monitoring even the little things such as a trip, a fall or your headphones being pulled out.

Using a 'Smart Trigger' it then gives you 15 seconds to respond. If you don't tell the app you're ok, it sends out a loud alarm, notifying your virtual companion who have the option to tell the police.
